"Guessing the Periodic Signal"

Supposing we are given a signal x(t)


1) x(t) is real and odd


2) x(t) is periodic with period T = 2 and has Fourier coefficients $ ak $


3) $ ak = 0 $ for |k| > 1


4) $ \frac{1}{2} * \int_{0}^{2} |x(t)|^2 dt = 1 $


We are told to specify two different signals that satisfy the given conditions.
